Gunnar of Djurby

Gunnar of Djurby (850-) was the Danish ruler of Djurby (Derbyshire) during the late 9th century AD. During the 880s AD, Gunnar - described by some as the "consummate imperialist" - embarked on a bold war of conquest against Mercia, creating an empire which stretched from Nottinghamshire in the east to Wales in the west and from Greater Manchester in the north to Derbyshire and Cheshire in the south.
